Ok, so I don't remember right:

Their explanation doesn't make much sense, but the connectors still
work fine for UHF.


Yes they do, I use them up to 1900 mhz, short runs of cable, with no
problems. Not sure what their loss is, but they are quite a bit
cheaper than N connectors.


Maybe you can explain that to Leland -- according to his calculations
and internet research, they shouldn't work at all at those freqs.

Why don't you show everybody where I said they don't work. Same goes for the
link I sent you. That person did exactly what you proposed, used an
expensive RF network analyzer, and reached conclusions just the opposite
from yours.

I'll let people read the paper for themselves. Nowhere does the aurthor say
"they shouldn't work at all at those freqs", which is a flat out lie on your
part.

It was a response to your comment in email about how I believe
impededance bumps don't exist, something which I never said or even
implied.

It was a comment you made in a posted reply to Lancer. I have never said
"they don't work at UHF", those are your words not mine. They are NOT
RECOMMENDED for use at UHF because of the impedance bump they cause in the
transmission line. The higher the frequency the worse the problem gets. The
only connector that looks like the UHF is the "Mini-UHF" which IS a constant
impedance connector. In fact Amphenol states they should be good up to 2.5
GHz.

Link for spec's for UHF connectors, pay attention to the impedance and
recommended frequency application range.

http://www.amphenolrf.com/products/uhf.asp

Now compare that with the spec's for the "Mini-UHF" connector.

http://www.amphenolrf.com/products/miniuhf.asp

Then for comparative purposes with the "N" connector.

http://www.amphenolrf.com/products/typen.asp

Amphenol would not be manufacturing the last two connectors if the UHF
connector was as good as you implied. For those who think a quick and simple
SWR test proves the suitability of the connectors should read the link below
which does a good job explaining how a so-called SWR reading, or using
forward and reflected power reading, can lead you down the garden path if
the test isn't done right.
